  • Low voltage cutoff circuit for an electrochemical cell
    Patent number: 7586292
    Abstract: The present invention is an electrical circuit that disconnects an electrochemical cell from a load when the cell's voltage descends to a predetermined value. The present invention is also applicable to a battery configuration and its corresponding electrochemical cells. The predetermined value is designed to decrease the chance that the cell or battery will become unstable while connected to the load.

  • Wander alarm
    Patent number: 5933083
    Abstract: The present invention operates when a fastening means connects to a patient. The fastening means attaches to one end of a flexible member and at the other end of the flexible member is a spherical member. The apparatus limits the distance the patient can move. This predetermined distance is the length of the flexible member, the fastening means and the spherical member. The spherical member is removably mounted to a control housing. The control housing has a signalling device that generates a signal when the patient moves beyond the pre-determined distance. The spherical member triggers the signalling device when the patient, from any direction, moves beyond the pre-determined distance which exerts a pulling force upon the spherical member.
